Send data from Python to Javascript (JSON)

Question

I know JSON to solve this problem, but I have problems in implementing it. Here is the detail of my approach:

1. Data are calculated in Python
2. Since the

Answer 1

you don't have to "implement" JSON, python comes with a built in lib, called simplejson, which you can feed with normal dicts:

try: 
  import simplejson as json
except:
  import json
out = {'key': 'value', 'key2': 4}
print json.dumps(out)

EDIT: as tadeck pointed out, simplejson should be more up-to-date and is not equal to json, but there is a chance, simplejson is not available due to it is maintained externaly

EDIT 2: based on the discussion in this answer and the discussion on the page, i think, the best approach would be something like that:

python

# [...] generate dynamic data [...]
html = html + template.render (templatepath + 'outputpage_start.html', {})
html = html + template.render (templatepath + 'outputpage_js.html', {})               
html = html + """<table width="500" class='out' border="1" data-dynamic="%s">""" % json.dumps(your_generated_data_dict)
#tr/td elements and templating as needet
self.response.out.write(html)

javascript

$(function(){
    var your_generated_table = $('table'),
        dynamic_data = JSON.parse(your_generated_table.attr('data-dynamic'));
});

you then have the exact same structure your python dict has as a javascript object.
